2022 Jeep Compass False Park Assist Warning TSB

Owners of the 2022 Jeep Compass equipped with the P&P Park and Unpark Assist System (Sales Code XPK) and Front Fascia Parts Module (Sales Code X8W) may notice an unexpected warning. This bulletin, TSB 08-147-24 REV. A, issued on August 8, 2024, addresses a specific software-related problem.

This updated bulletin supersedes the previous TSB 08-147-24 dated June 26, 2024. It provides revised instructions for addressing the false park assist warning issue.

Symptoms

The primary symptom associated with this technical service bulletin is a "False front park assist warning when no obstacle present in front of vehicle." This means your 2022 Jeep Compass may indicate an obstruction in front of the vehicle even when the path is clear. This can be distracting and may lead to unnecessary caution or confusion while parking or maneuvering at low speeds.

Diagnosis

To diagnose the 2022 Jeep Compass false park assist warning, technicians will use a Scan Tool (wiTECH) in conjunction with the Diagnostic Procedures available in the DealerCONNECT/Service Library. This process helps verify that all related systems are functioning correctly. If any Diagnostic Trouble Codes (DTCs) or other symptom conditions are present beyond the false park assist warning, they must be recorded and addressed before proceeding with the software update. The repair procedure is specifically for vehicles exhibiting the described false park assist warning symptom.

Repair Procedure Summary

The resolution for the 2022 Jeep Compass false park assist warning involves reprogramming the Park Assist Module (PAM) with the latest available software. This is a crucial step to correct the underlying software anomaly causing the false alerts. After the reprogramming, all Diagnostic Trouble Codes (DTCs) that may have been set in any module during the reprogramming process will be cleared using the wiTECH application.

Following the software update and DTC clearing, technicians must confirm the repair. This involves using traffic cones to verify that the park assist system is operating correctly and that no false alerts are detected. If the system functions normally, the bulletin's procedure is complete. If issues persist, further diagnostics will be performed.

Required Tools

For this repair, technicians will need a wiTECH diagnostic tool or an equivalent system. This tool is essential for communicating with the vehicle's modules, performing the software flash, and clearing any DTCs that may arise during the process.

Important Warnings

During the reprogramming of the Park Assist Module (PAM), specific precautions must be taken to ensure a successful update and prevent potential damage:

• Battery Charger: It is mandatory to install a battery charger to maintain stable voltage. The battery voltage must not drop below 13.2 volts during the flash process. Additionally, the charging voltage must not exceed 13.5 volts.
• Interrupted Flash: If the flash process is interrupted or aborted for any reason, it must be restarted from the beginning. Failure to do so could lead to module corruption or incomplete software installation.

Owner Action

If your 2022 Jeep Compass is experiencing a false front park assist warning, you should schedule an appointment with an authorized Jeep dealership. The repair, which involves reprogramming the Park Assist Module (PAM) software, is reimbursable under the provisions of the vehicle's warranty. The labor operation number for this service is 18-20-05-Y6, and the failure code to be used by the dealer is CC (Customer Concern).
